Spectroscopy of ^44,46Ti with the Binary Reaction Spectrometer and Euroball

A first experiment was performed with the Binary Reaction trigger Spectrometer (BRS) for Euroball, as second last experiment of phase III. The reaction ²⁴Mg(³²S, ⁵⁶Ni*) at E = 163.5 MeV was chosen in order to populate a specific hyperdeformed resonance state in the compound nucleus ⁵⁶Ni* at E* = 84 MeV (J^π = 46⁺) and to investigate the spectroscopy of its binary descendents. The experimental setup combined the γ-detector array Euroball III, without the phase I Ge detectors, the two large-area gas detector telescopes of the BRS at forward angles and 31 of the 40 detectors of the 4π silicon ball EUROSiB (now called ROSiB) at backward angles. We report on results of binary reaction triggers collected with one BRS telescope. Binary events are separated from evaporation residues due to (i) the large laboratory scattering angles of the detected reaction fragments, the opening angle of the BRS telescope being θ = 12 ° – 46 °, and (ii) by means of particle identification in the telescope. In this paper channels with emission of ⁸Be plus two protons and of ¹²C will be discussed.
